Introducing the New Codex for (almost) everything

I think you’re close to the real reason they prioritize macOS. They likely develop first on Linux for internal testing. Then they move to macOS, since it’s a Unix-based system , which makes porting relatively straightforward. Finally, they support Windows. Although WSL2 is a great tool, not all Windows developers are familiar with it, so they still need to provide native Windows support—which is more challenging when starting from a Linux environment.

Can anyone confirm whether this analysis is correct?
